Hi,
I have a fresh (few days old) install of Ubuntu Desktop 20.04.3 on an Intel 11 NUC (NUC11PAHi7). The WiFi interface is disabled in the BIOS so the only physical network interface on this machine is the NUC's built-in 1gbe NIC (enp88s0). This NIC is on two different subnets (VLANs). Here is my netplan config:
ip r output:
default via 10.0.0.254 dev enp88s0.100 proto static
10.0.0.0/24 dev enp88s0.100 proto kernel scope link src 10.0.0.3
10.1.0.0/24 dev enp88s0.101 proto kernel scope link src 10.1.0.3
For some reason I am unable to SSH/VNC into this machine from the 10.1.0.0/24 network to the 10.0.0.3 interface (specifically from my MacBook Pro's WiFi at 10.1.0.32). It just times out (the firewall sitting in-between these subnets has this traffic permitted & ufw is disabled on Ubuntu). SSH/VNC work just fine when on the same subnet (so 10.1.0.32 to 10.1.0.3 or 10.0.0.0/24 to 10.0.0.3).
Thanks,
->g.
